Him188 ba461f8c62 [AArch64][GlobalISel] Legalize fp128 types as libcalls for G_FCMP (#98452) ...

- Generate libcall for supported predicates.
- Generate unsupported predicates as combinations of supported
predicates.
- Vectors are scalarized, however some cases like `v3f128_fp128` are still failing, because we failed to legalize G_OR for these types.

GISel now generates the same code as SDAG, however, note the difference
in the `one` case.
